Nuclear fusion of hydrogen into helium occurs in the .
1. energy moves through the sun's by means of the rising of hot gas and falling of cooler gas.
2. nearly all the visible light we see from the sun is emitted from the .
3. most of the sun's ultraviolet light is emitted from the narrow layer called the where temperature increases with altitude.
4. we can see the sun's most easily during total solar eclipses.
5. the is the layer of the sun between its core and convection zone.

Using software, a simulation of a javelin being thrown both on earth and on the moon is created. in both cases, the velocity and angle of projection are kept the same. on earth, the javelin covers a distance y. what distance would it cover on the moon? (the moon’s gravity is about 1/6th that of earth.) a. 6y b. 6/y c. y/6 d. (y+6)2

Because air contracts as it cools, the air pressure inside a freezer is typically lower than on the outside. why do ice cubes inside a freezer tend to shrink over time? a. the ice dissolves oxygen from the air, forming a denser crystalline matrix.b. the ice reacts chemically with carbon dioxide in the air, forming gaseous carbon compounds.c. the ice melts, and then the liquid freezes as ice crystals on the bottom of the freezer.d. the ice sublimes, and then the water vapor deposits as ice crystals on the sides of the freezer.
